I was just depositing some cash into a Washington Mutual account an hour ago, and the atmosphere was unmistakably edgy. A long line of people, anxious looks on some of the faces, a vaguely nervous undercurrent of one form or another. Washington Mutual went under a few days ago and was bought up by JP Morgan Chase on 9.26. There was a fat guy jabbering excitedly to a friend and making no attempt to hide his anger at bank employees behind the glass who were sitting at desks and not at teller windows. The vibe was on the sullen side. No jokes, no smiles, no chit-chat.
